PDF Converter & PDF Tools
PDF describes a page as a fixed arrangement of text, vector graphics and images. That is what makes it reliable for sharing finished documents, and what makes it awkward to edit — it stores positioned glyphs, not paragraphs.
These tools use pdf.js to read and render PDFs and pdf-lib to write them, both running in your browser. Contracts, invoices, medical records and anything else confidential stay on your device.

Why PDFs are hard to edit
A word processor document stores structure: this is a heading, this is a paragraph, this is a list. A PDF stores the outcome: this glyph at these coordinates, in this font, at this size.
Converting a PDF back to an editable document therefore means inferring structure that was never recorded — grouping glyphs into lines, lines into paragraphs, and guessing which lines were headings from their relative size. It works well for straightforward prose and poorly for multi-column layouts, forms and complex tables.
Scanned PDFs contain no text
A scanned document is a stack of photographs wrapped in a PDF. There is no text layer at all, which is why you cannot select or search the words in it.
Text extraction on such a file correctly returns nothing, and FileTools360 says so rather than handing back an empty file. Optical character recognition is what you need — it reads the pictures and produces text, with accuracy depending heavily on scan quality.
Why compressing a PDF sometimes does nothing
PDFs are large for different reasons. If the bulk is high-resolution images, re-rendering pages at a lower resolution shrinks the file dramatically. If the bulk is text and vector graphics, it is already efficiently stored and there is little to remove.
Because this approach rasterises pages, it also costs you selectable text, links and form fields. FileTools360 keeps your original rather than handing back a file that is larger or worse than what you started with.
